Shimano Synchronized Shift
Shimano's XTR Di2 M9050 family features the optional Shimano Synchronized Shift, allowing for customizable synchronized front and rear shifting via a single FIREBOLT shifter. By simplifying the rider interface, shifting a mountain bike will have never felt so natural.
The M9050 derailleurs communicate gear position and automatically execute front and rear shifts when a rider asks for a sequentially larger or smaller gear. This improves efficiency by minimizing time spent on smaller chainrings and cogs.
Thanks to the programmable options with the Di2 platform, riders can choose when front shifts occur based on terrain and personal preferences. An audible alarm will warn of an upcoming front derailleur shift so that a rider can choose to remain in a given gear. Additionally, on a mountain bike with both front and rear FIREBOLT shifters installed, the rider can manually override shifts at any time, creating perfect cadence control. With Shimano Synchronized Shift your experience on a mountain bike has never been this intuitive, this personalized, this connected or this focused.
Shimano’s FIREBOLT customizable shift button placement is determined entirely by human ergonomics. This means that the shifters are now exactly where your thumbs naturally rest. Shifts can happen more quickly, allowing you to adjust to the terrain and your desired effort like never before, taking Shimano’s Rider Tuned concept to an entirely new level.
